The miniDSP Dirac software runs on a Mac now (they issued an update a few (?) months ago).
The second definitely won't work. For "normal" you would have to find out what exactly that means. If you can find a link to the manual I'll take a look if you like. Some devices will only do stereo (not multichannel) output as PCM.
No, it won't, because it will be receiving linear PCM which is not an encoded format, it is just uncompressed audio. Basically, the idea is that the player/source does the decoding, then feeds it through to the nanoAVR (either version) in linear PCM. When then is sent on to the AVR in linear PCM. So the AVR doesn't know what the original format on the disc was.
The HD is all manual setup. You can use the REW Auto EQ to help if you wish. Dirac is much more automatic but still allows control over the target curve. Having gone through the whole nanoAVR HD setup procedure, I do have to say that it was quite time consuming and the Dirac approach (once you figure out where the mic goes etc) is much less work.
